Hi @Paveldeg
HDMI on M1 mac does not allow DDC control, so you are currently using software mode (brightness changes only after 50% if ddc is shown as enabled in preferences) which does not allow volume control.
Please see this issue for more infos on the problem : https://github.com/MonitorControl/MonitorControl/discussions/750

hi @the0neyouseek , you misunderstood that.
he was talking about the Macbook, not the Mac mini you mentioned.
I have the same type of issue, and although I have the different monitor model than his, I can't control the volume either, only the brightness(via hardware control).

Hi @CzBiX
No I didn't misunderstood, he was talking about an M1 MacBook Pro. This issue affect all Apple Silicon devices so far, including Mac minis and MacBooks.
If you're using the HDMI port, DDC control is blocked and MonitorControl uses software dimming thus is not able to control the monitor volume

@the0neyouseek Sorry, I didn't look closely enough. The owner is connected to the HDMI port.
My issue is not the same to this thread.
